S15: all detection data of pretreatment module to same frequency are tentatively encoded, and be sent to field data storehouse and store temporarily; All detection data comprise channel A transmit coherent detection data and channel B upgrade after channel parameter;
S2: data matching unit carries out Data Matching process to the data in field data storehouse;
S3: the identical outer field signal after matching treatment is sorted out by Data classification statistic unit respectively, isolates the kind of signal, generates data statistics form;
S4: data analysis unit, according to the data statistics form generated, analyzes the detected value of various data and the relevant information of the frequency of occurrences, generates the analysis diagram corresponded;
S5: data message dependent processing unit determines the reasonability that outer field signal exists and degree of safety according to analysis diagram, processes timely to harmful outer field signal.
